SUNDAY’s Giants-Pat riots battle has all the earmarks to be the most-watched Super Bowl in history, experts say.

And with last year’s game averaging a staggering 93.1 million viewers, that’s saying a lot.

“I’m in the camp that believes it’ll possibly be the hugest Super Bowl ever,” says ratings analyst Robert Seidman, who runs tvbythenumbers.com.

Seidman says it’s all about the undefeated Patriots trying to become the first team in NFL history to go 20-0.

“We seem to like things of a historic nature, things that have never been done before,” he says. “And even for a sports event this will ring true. My thinking is, if this game doesn’t bust 100 million viewers, nothing will.”

Media analyst John Rash, of Minnesota-based Campbell Mithun, agrees – to a point.

“There are a confluence of factors coming together to give the game the opportunity to be the highest-rated in history, including two of the country’s top five markets and the historic status of potential Patriots perfection,” he says.

“But much depends on the game itself. If it’s a blowout . . . there could be some early tuneout.

“But you’ve got the [Bill] Belichick coaching controversy, [Patriots receiver] Randy Moss being a polarizing figure and the seeming role-reversal of the Boston-New York rivalry,” he says.
